On measuring the Quantum Universe
David Vasak, Johannes Kirsch, Juergen Struckmeier
We present a theoretical analysis of the WDW approach to quantum cosmology extended to gravity theories with torsion. The dynamics of the FLRW universe is formulated as a classical…
Covariant Canonical Gauge Gravitation and Cosmology
David Vasak, Johannes Kirsch, Dirk Kehm +1
The covariant canonical transformation theory applied to the relativistic Hamiltonian theory of classical matter fields in dynamical space-time yields a novel (first order) gauge f…
Generic Theory of Geometrodynamics from Noether's theorem for the Diff(M) symmetry group
Jürgen Struckmeier, David Vasak, Johannes Kirsch
We work out the most general theory for the interaction of spacetime geometry and matter fields -- commonly referred to as geometrodynamics -- for spin- and spin- particles.…
Canonical Transformation Path to Gauge Theories of Gravity
J. Struckmeier, J. Muench, D. Vasak +3
In this paper, the generic part of the gauge theory of gravity is derived, based on the action principle and on the general principle of relativity. We apply the canonical transfor…
